TWEEZERS.

Specification of Letters Patent.

Patented May 31, 1921.

Application filed June 22, 1920. Serial No. 380,880.

To aZZ w ham it may concern:

Be it known that I, ERNEST H. MnroALr, a citizen of the United States, and a resident of Marlboro, in the county of Cheshlre and State of New Hampshire, have invented a new and Improved Tweezers, of which the following is a full, clear, and exact description.

This invention relates to improvements in tweezers, an object of the invention belng to provide an improved construction of tweezer cut from a single metal blank forming a pair of spring jaws movable toward and away from each other by means of an improved operating lever.

A further object is to provide a tweezer which is cut from a blank of sheet metal so that the jaws thereof are movable edgewise and provide a removable fingenoperating lever for controlling the operation of the jaws.

A further object is to provide a tweezer of the character stated'which can be manufactured and sold at an extremely low price and which will most efficiently perform the functions for which it is intended.

lVith these and other obj ects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out 1n the claims.

In the accompanying drawings- Figure 1 is a view in elevation of my improved tweezers showing in dotted lines the position of a hand controllmg the operatlon thereof.

Fig. 2 is a plan or edge vlew of the tweezer showing a portion thereof in section.

Fig. 3 is a view in transverse section on the line 33 of Fig. 1.

My improved tweezer 1 is cut or stamped from a relatively thin sheet of steel or other elastic metal or material formlng a pair of jaws 2 and 3, said jaws at their inner end or point of juncture cut in the form of a curve or segment 4 and having an integral rearwardly projecting tongue 5, the latter provided with an opening 6 of general conicalshape so that this tongue with its conical shaped opening 6 can be conveniently used for removing blackheads.

The jaws 2 and 3 are outwardly or conveXly curved at their outer edges, as shown at 7, and a finger lever 8 is employed to move the jaws toward each other. Th1s lever 8 1s provided with a slot 9 which receives the pair of jaws 2 and 3 and the slot is of a wldth but slightly greater than the thickness of the metal of the jaws so as to prevent possibility of the jaws being moved out of alinement.

The jaw 3 is provided with a lug 10 forming a shoulder back of which one end of the lever is adapted to fulcrum and the other end of the lever is bent rearwardly forming a finger or thumb recess 11 so that when the lever is pressed inwardly by means of the thumb of the user as indicated in Fig. 1, the jaws will be forced toward each other by reason of the cam action of the lever against the convex edge 7 of j aw 2 and when pressure is relieved on the lever 8, the jaws will spring to open position.

It will be noted that the lever and the 'tweezer are two separate independent parts which can be readily assembled by positioning the slotted end 9 of the lever over the ends of the jaws until the lever engages back of the lug or shoulder 10, and the main portions of the tweezer can be stamped from sheet metal so that the entire construction can be cheaply manufactured and assembled. Furthermore, the walls of the slot 9 maintain the jaws of the tweezer in alinement and insure their proper engagement when pressed together by means of the lever.

Various slight changes might be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A tweezer,'comprising a pair of integral jaws spaced apart, one of said jaws having a shoulder thereon, and a lever having a slot therein receiving the pair of jaws and located back of and fulcruming against said shoulder.

2. A tweezer, comprising a pair of vintegral jaws spaced apart, one of said jaws having a shoulder thereon, and a lever having a slot therein receiving the pair of jaws and located back of and fulcruming against said shoulder, said lever having a rearwardly projecting finger or thumb engaging portion. I

3. A tweezer, comprising a pair of integral jaws spaced apart, one of said jaws having a shoulder thereon, and a lever having a slot therein receiving the pair of jaws and located back of said shoulder, said jaws having outwardly or convexly curved outer edges whereby the rearward movement of the lever operates to force the jaws together.

4. A tweezer, comprising a pair of integral jaws spaced apart, one of said jaws having a shoulder thereon, and a lever having a slot therein receiving the pair of jaws and located back of said shoulder, said lever having a rearwardly projecting finger or thumb engaging portion, said jaws having outwardly or convexly curved outer edges whereby the rearward movement of the lever operates to force the jaws together.

5. A tweezer, comprising a pair of integral jaws stamped from sheet metal and movable edgewise toward and away from each other, a lever having a slot therein receiving the jaws, said slot of a width but slightly greater than the thickness of the jaws, whereby the jaws are maintained in alinement by the walls of the slot, and a lug on one of said jaws forming a shoulder against which one end of the lever fulcrums.

manner HENRY METGALF.
